Description

  The present invention relates to an apparatus for controlling an air conditioner using a programmed microcomputer, and more particularly to control during long-term use.

  Generally, household electric appliances including air conditioners have a standard design use period, and if the use is continued beyond the use period, there is a possibility that an unforeseeable malfunction or failure may occur.

  Conventionally, this type of air conditioner control device uses an inspection time when the integrated value of the operating time of the entire system or the integrated value of the energization time of the main components exceeds a predetermined value. If the operation time or energization time exceeding the inspection time reaches a predetermined time, the operation is forcibly stopped and the subsequent operation is prohibited (for example, patent document) 1).

  FIG. 3 shows a flowchart of a program executed by the microcomputer of the conventional air conditioner control device described in Patent Document 1. In FIG. 3, only when the operation is in step 301, the process proceeds to step 302, where the operation time T is integrated and stored in the nonvolatile memory. When the integrated value of the operation time T exceeds the designed standard use period T0 in step 303, the operation proceeds to step 304 and the operation is stopped. Only when the operation is being performed in step 306, the process proceeds to step 307, where the operation time T is integrated and stored in the nonvolatile memory. Then, when the integrated value of the operation time T exceeds the total of the designed standard use period T0 and the predetermined time T5 in step 308, the process proceeds to step 309 and the subsequent operation is prohibited.
